That would suck to have just 1 favorite game. It's impossible to answer that question.

That's easy: PS2. You could play both the new PS2 games on it, AND your existing PSOne games? How could it ever get better than that?

Castlevania - Symphony of the Night. & PS2 console with its backward compatibility & PSP for fav handheld.

I'll answer the favorite console part - SNES. Many great games on that sucker.

Baldur's Gate 2 - Shadows of Amn, but building on the Original of course that was totally awesome too.

Quite regrettably, still after oh so many many years, this title remains to me the culmination of magnificence of story telling, of characters of substance that one grows very fond, of totally enjoyable game engine.

Braid.

Baldurs Gate 2 too,
Without Throne of Bhaal.

Its such an fascinating game. A deep story, many little things that happen in a magical world. Never again I have experienced such an open world which fits together so well .

Doom, I guess it's because it was the 1st game I ever played, still great though.

Hoshigami: Ruining Blue Earth

Can't pick just one. Too many games, too many genres, way too many things to take into account!

My favorite console is the PS2. My favorite handheld is the GBA.

Favorite game ever: Super Metroid
Favorite console ever: Super Nintendo

Same here but I don't think you can pick one that is the best in everything, in every possible situaton including time.

My Personal Fav is Pokemon Blue.

My favorite console is the XBOX 360

Favorite handheld is the Game boy advance SP.

Guess I'll choose a game for the sake of this thread.

Shining Force I

Still need to get to the sequel. Have it on my gamersgate account so I'll get to it later.

Two of my favorites: Deus Ex and Final Fantasy Tactics.
